    again strange behavior

    Hi,

    I finished my application butonce again i have some strange behavior
    with XML/text functions...

    for example, here below is a function which worked perfectly till now
    and now generate an error :
    "An unhandled exception of type 'System.NullRef erenceException ' occured
    in Unknown Module.
    Addition information : object reference not set to an instance of object"
    when i click on break, i can not get anymore information, but if i click
    on continue, my application works perfectly... :-(

    this error is raised after few sw.WriteLine commands...
    i have the same issue if i do :

    dim doc as XMLDocument
    doc = new XMLDocument (here occured error)

    where could be the problem ?
    from my point of view, some options in application could have such
    impact but which ones ?

      Re: again strange behavior

      Hi,

      I dont know why you are getting the error at the new xmldocument
      line. I would use the xmltextwriter class to write the xml document instead
      of a streamwriter.
